Why resign when you lose your queen?
When/if to resign is all a matter of personal preference, so long as you aren't unnecessarily stalling. Good luck with your chess!
Of course at your level it is quite possible your opponent could blunder their queen right back, so material advantage is not as significant.
When I was 800 I blundered my queen in several games and came back because my opponent made even more egregious blunders.
It no longer happens because my opponents are actually decent, and so can reliably convert such an enormous material advantage into a win.
